HYDROCARBON-BL IRNER.

SPECIFICATIONf rming part of Letters Patent No. 757,027, dated April 12,1904.

Application filed March 28, 1903.

To aZZ whom it may concern:

Be it known that I, THOMAS H. DELANEY, a citizen of the United States,residing at N or' wich, in the county of New London and State ofConnecticut, have invented a newand useful Improvement inHydrocarbon-Burners,of which the following is a specification, referencebeing had to the accompanying sheet of drawings.

My object is to provide a convenient and economical form ofhydrocarbon-burner for use in stoves, ranges, and house-heatingapparatus, and particularly to so improve such burners that perfectcombustion shall be assured, thus overcoming the objectionable smoke andodor now .so common in this class of burners.

In order to explain my invention clearly, I have provided the annexeddrawings, in Which Figure 1 is a side elevation of a burner embodying myimprovements, and Fig. 2 is a plan view of the same. My improved burneris built up of three superimposed sections or parts, and in Fig. 3 Ihave shown the burner with the cover-plate removed. In Fig. 4: I. haveshown it with the cover-plate and retortcasting removed, thus disclosinga plan view of the pan: Fig. 5 is a cross-sectional view of the completeburner, taken on line 5 5 of Fig. 2; and Fig. 6. is a similar View takenon line 6 6 of said Fig. 2.

In the drawings the lettera indicates the base-section, which is apan,"b the intermediate section'or retort-casting, and c the top sectionor cover-plate which fits over the retort-casting, these sections beingpreferably of cast metal.

The base-section a is formed substantially as a rectangular pan withupright corner-posts a,upon which the intermediate section b rests, theposts being of such height that a considerable open space is providedbetween the base and intermediate sections, through which space theflames may pass outward and contact with the adjacent alls of the stoveor range when the burner is in use. The bottom of the intermediatesection is set in somewhat, as seen in Fig. 1, to receive the describedcorner-posts 0,. The upper portion of section b is Serial No- 1&9,958.(N0 model.)

formed with a longitudinal channel or recess 6, that is located near oneside of said section and serves as a conduit through which a plentifulsupply of fresh air is introduced into the burner,as I will explain morefully later. The channel I) is connected with the outside atmosphere byan inlet-pipe 0Z. The intermediate section b is also formed with acentral transverse chamber 6 into the lower part of which an oil-supplypipe 6 leads, as seen in Fig. 5, and in the pipe eat some convenientpoint outside the burner is a valve 6, by means of which.

the flow of oil into the chamber 6 may be controlled. Connected with thecentral chamber,

6 are oppositely-extending channels F, that connect with like channels6* at the ends of the said section b, as is best seen in Fig. 3. On theopposite sides of the central chamber I 6 (within the inclosure formedby said chamber and the channels 6 b b) are openings 6 b, and in thecenter of each of said open 1ngs 1s a vertical pipe-section g, Whoselower ends-are open, as is clearly seen in Figs. 5 and 6. These pipes 9form mixing-tn bes. A short pipe 9 connects each of said vertical pipeswith the described air-conduit b, and the'up.

per end of pipe g is connected bya pipe 9 stricted opening in the formof a plug g having a very small central perforation.

The top section 0 and the intermediate sec? tion Z) are secured togetherby a number. of

. bolts or screws it.

When my described burner isin service, the

of oil, (preferably crude or refined petroleum.)

pipe 6 is connected with a suitable reservoir When it is desired tostart a fire, a piece of.

paper or oil-saturated rag is first placed -underneath the centralchamber and lighted. This immediately warms up the bottom and side wallsof said chamber Z), so that when a small jet of oil is introducedthrough the inlet-pipe 6 said oil in seeking to spread over the bottomof chamber 6 is vaporized and in seeking to escape passes through thechannels 6 into the end channels 5* and thence escapes through the pipesg -into the vertical pipes g. The rapid accumulation of vaporized oil inthe channels I2 6 and 6 creates a considerable pressure, so that saidvapor is forced through the small opening g into the vertical pipe whereit mingles with a jet of air introduced through the pipe g, thusproviding an inflammable gas that burns freely at the lower or dischargeends of the pipes 9. These flames impinge on the bottom of thebase-section a and spread in all directions, passing outward through theopenings between sections a and b on all sides. The entire structuresoon becomes cherry-red and radiates intense heat.

Each of the pipes 9 includes a cut-off valve g and preferably ascrew-plug 9 through which the interior of the vertical pipes 9 may bereached and cleaned,if necessary. The cutoff valves provide convenientmeans for shutting off, either wholly or partly, either of the burners,thus making it possible to shut off at will half of the oil consumptionand to correspondingly modify the fire.

It will thus be seen that I provide a burner in which the oily vapor andair are mingled before they are brought into contact with the flameinstead of injecting or dropping the oil into a retort where itburnsbefore being suitably mingled with air, as has sometimes been done.My present arrangement, with means for controlling the inflow andmingling of the vapor and air, enables me to proportion and regulate thesame so that perfect combustion is attained with theleast possible useof oil.

Having thus described my invention, I claim 1. In a hydrocarbon-burnerthree superimposed sections, a base-section or pan, cornerposts, anintermediate section or retort-casting resting upon said corner-postswith an airspace therebetween, the bottom of the retortcasting being setin to receive said cornerposts, said retort-casting being formed with acentral transverse chamber, oppositely-extending channels connectingwith said central chamber and with like channels at the end of saidsection.
